Design spacing of and placing of sprinklers proposed / considered is baywise. Reason of going with the above:-gives me wider coverage compare to normal K5.6 sprinklers and lesser amount of piping.-having nearly 7 bar pressure at tapping point.If yes then:-what will be minimum number of sprinklers required to be considered to satisfy design area requirement.-what will be criteria to decide minimum k factor of the sprinkler.-same sprinklers can be used for area’s having ac ducts.Finally your say best solution to protect car parking area.Awaiting your reply.Thanks & Regards,
